“The Philips SHE3590 headphones were listed on the Head-Fi Headphone Buying Guide. They are inexpensive and widely available. Most Australian electronic retailers stock them and they cost about AUD15. I bought these (in white) to replace my lost AKG IEMs (which I have since found again!).
Build quality is cheap and plastic looking. Nobody will think to steal these headphones and you...” --stweb

“Got these on a sale, and was very pleasantly surprised. Originally, I was looking for something that isolates well and does not sound tiring for use in the office, but ended up using them as my first choice HP (instead of Alessandro MS1, Porta Pro, KSC55).
I have been using them with uDac2, 2nd gen iPod nano, and Audigy 2 ZS. They are easily driven by any of these...” --gvz

“
This IEM is definitely the best bang for the buck! Basshead person should purchase it without a doubt. Even it's higher brother, Philips SHE9800 didn't able to match the sound quality of this IEM! :D
It produced very deep punching bass and high definition clarity on mid and treble. It feels like you have your own built in sub-woofer inside this IEM! Comfort to use in a long run,...” --chrone

“As for any 'flat EQ' speakers these IEMs lacks a bit of energy and sparkle (not definition, they have plenty of it!), not everything is rendered precisely since they try to do everything (in particular I do not like the rendition of cymbals), so they do not excel in any particular area except for soundstage (I noticed that it's a common problem with IEMs that try to expand the soundstage)....” --Tetsuro P12

“
i dont want to say too much cuz its nearly discontinued , and its hard to find one , it was even then , the comfort is awesome ,the sound stage is the biggest i have ever heard even bigger then my cx500 . i own two of these , so you can think how much i love them .. good bass , nice mids , good highs and the best thing is its really fun to hear these ..
onw thing i would like to...” --suman134

“I found these back in last year when I was on the funs of looking for good quality budget IEMS. I was very impressed by these back then, and I put it away for a while. Today, I got back to it, and I thought I better review it, and let more people know about it sound quality
Conclusion: At sub 30$ with this much quality is un-beatable. Especially in the sub-bass,...” --Whitigir

“ get one if you can , come with a small plastic carry case too and about SQ its a 3580 with a bit more forward mids and smaller bass . bass is as deep as 3580 , nice detail , good mids , vocals are not most enjoyable but what can you ask for this price ? instruments are there thankfully if not clearly separable its good enough , sound stage is okay , nice highs though , a bit grainy but...” --suman134

“While browsing through my local electronic store I came upon these Philips IEMs. G reviews on the forums persuaded me to pick this one up at €14,95
I stopped buying cheap headphones years ago when high quality portable audio became more portable and affordable. Before that time I was a Philips fan, back then I thought that Philips had an honest sound in their cheap earbuds (I hated IEMs).
But...” --Mactire

“As list in the summary, I don't like this product, and I will not buy any product from Philips because of the post-sale service.
After I tried replacing all of the ear-pieces in the box, I finally confirm that the sound quality of S2 is bad.
First of all, I could not hear any bass instrument in most of music. It's less even than V-Sonic VS1D.
And the High-Mid is...” --Jemuillot

“
For an affordable in ear monitor with built in mic, I'm surprised by the sound quality it produced. This phone is for basshead person. Hehe :D
It produces good enough deep bass without distorting the mid and treble. The deep punching bass and high definition clarity is somewhat one level below its older brother, Philips SHE9700. The mic is also compatible with Samsung Galaxy Nexus....” --chrone
